This Is Why The iPhone’s Screen May Always Be 3.5 Inches

Why does the iPhone have a 3.5-inch screen? Why do larger smartphones feel awkward on your hand? Dustin Curtis reckons he has the answer:

Touching the upper-right corner of the screen on the Galaxy S II using one hand, with its 4.27-inch screen, while you’re walking down the street looking at Google Maps, is extremely difficult and frustrating. I pulled out my iPhone 4 to do a quick test, and it turns out that when you hold the iPhone in your left hand and articulate your thumb, you can reach almost exactly to the other side of the screen.

His graphic shows this clearly. It makes some sense. And explains why we may not see any larger screen iPhones. Still, people do perfectly fine with big screen phones like the Galaxy S II, so who knows what Apple could do in the future. [dcurtis]

    You must have small hands then. I bought the Galaxy S2 on friday and it is amazing and yes its a little bigger, but not in the awkward zone at all.

      Guys – all this BS about MUST HAVE A BIGGER SCREEN have to stop. There is room for every phone in the market. Obviously some people like a huge screen, which make for a huge phone. Others, like me, prefer the slightly smaller screens which make for a smaller phone. It doesn’t make one better then the other, only different.
      As I said – I prefer the smaller screen on the iPhone not because its an iPhone but because of its size.
      BTW, sone of my friend pointed out to me that the Apple os, because it is apple, is more secure as opposed to the Android, which is Google, and by definition is an open system. Not as secure.
      So there – anyone can have the phone of their choice and no matter what – you are going to be happy with your choice.

    I agree there are downsides to a larger screen. But so too of smaller. Tho the clarity of the iPhone and ppi ATM is far better then any I far prefer my galaxy 2 to the iPhone 4 screen, and I have both. Adjusting positioning and getting a feel for the Samsung to use one handed takes a little more time. But that’s the beauty of iPhone..simple for more everyone to use…right from the start.

    I have a Nexus S wiith 4″ and have no problem at all. The phone fits comfortabely in my hand and I can touch all screen areas without trouble. I am a tall person so it goes I have long fingers. Maybe the issue here is you need to consider your hand size when buying a phone. The new fleet of android Gigantor >4″ screens may look pretty cool but may not be practical for you. I chose the Nexus s because it gave me a bit more screen real estate but wasn’t a monster in my hand or in my pocket.My father has a Galaxy S2, he does not seem troubled by the 4.2″ size. Again it’s choice and for me the 4″ screen is a pretty good fit.

    I’m sorry but this is some dodgy krap. Depending how I hold my phone, I have no problem getting my thumb right over to the far corners. That said, I can’t think of any reason not to hold it in one hand and use it with the other. I even use my 3.3″ Zune HD that way. Clearly that is why this clown is holding it in his left hand in the first place.

      You call him a clown, yet you use two hands to operate devices that most people only use one?

      Me personally, i don’t get the “MUST HAVE A BIGGER SCREEN!!!” obsession. Bigger screen = bigger phone, and frankly I don’t care to have massive phone. That said, the HTC Aria i was given from work was tiny and useless.

        @Scott said, “You call him a clown, yet you use two hands to operate devices that most people only use one?”

        When typing on a smartphone, the majority of people use two hands – either by typing using both their thumbs or hold the phone with one hand and peck with the other.

        One of the primary uses of a smartphone is to play games – the majority of which require two hands.

        MotorMouth isn’t the one I’d be calling a clown.

        Regarding the original post – I think it’s garbage unless he also provides a study showing that everyone has the same sized hand and holds it the exact same way.

        Also, with the plethora of multi-touch commands available why would the designers have single-hand usage as a core constraint?

    Look up bell curve in relation to hand sizes I’m sure apple did. I have the gs2 and it is a pain to reach a corner sometimes but that’s only 2% of the time and that 2% does not justify me buying a 3.5 inch screen over a 4.27inch screen.

        While this is an immensely sensible explanation, the sad reality is that apple are building the phone to a price point. Smaller screen equals less cost and more margin for the price.

    I have a Galaxy S2 and have noticed that I can barely use it with one hand. Fortunately if I adjust my grip I can reach everything, but I have noticed its a little on the big side, and infact I’ve been worning people I know with small hands that the Galaxy S2 is probably too big for them if they like using their phones one-handed.

    Depends how you hold it. As a Galaxy and iPhone owner (one for work, one for personal use) I have to say I prefer the iphone sizing. its just easier, more compact.

    The net on my Galaxy looks better though purely for the larger screen.

    If you hold your phone on your fingers rather than in your palm, while slightly more precarious, it should allow you to reach the entire screen. Just tried it with a 4.0″ Samsung Focus and I could reach further than the edge of the screen.

    mentioned this in a thread yesterday or the day before, and got labelled as “clutching at straws”. glad to see a post explaining the logic. if the iphone had smaller borders it could probably go up to 3.7-8. but then the resolution would have to go up to keep that pixel density the same and then you would end up with lots of ugly apps.

    Seems to be an arguement for not making the device larger as opposed to keeping the screen at 3.5″. If they reduced the bezel on the side and extended the display a bit vertically while not making the unit any larger, you’d have a fairly negligible different in finger coverage while being able to make the screen a bit larger. Not 4.2″ but I reckon you could get it to 3.8″ or so at least.

    So does that mean that apple is never going to come up with a bigger screen or they are going to wait till the human race is genetically fit for a larger screen size.
    I feel is a just a matter of getting used to a bigger screen. Humans can adapt and have done that for ages. I am sure there would have been a time when even a 3.5″ screen would feel big.
    Also why did these explanations not come out an year ago or before Apple released 4S?
